BRUSH.

Application filed August 23, 1918.

To all whom t may concern Be it known that I, JOSEPH GAssnR, a citizenof United States, residing at 27 Carrol street, Trenton, in the -countyof Mercer and State of New Jersey, have invented new and usefulImprovements in Brushes, of which the following is a specication.

The invention relates to brushing and scrubbing, and more particularlyto a device for accomplishing that purpose, and has for an object toprovide a rotary brush for use in brushing or scrubbing, and which isparticularly adapted for use in cleaning or scrubbingrust from iron orsteel.

Although the invention may be adapted for various purposes, Iparticularly employ my brush for use on the hulls of ships and the like,for removing therefrom any accumulated rust, barnacles, or other foreignmatter. To this end I provide a brush body which is preferably arrangedwith steel bristles, and which is rotated at a high rate of speed, inorder to effectively remove any incrustations that may have accumulatedon the sides of a ship or on steel plates.

In the further disclosure of the inven tion, reference is to be had tothe accompanying drawing, constituting a part of this specification, inwhich similar characters of reference denote corresponding parts in allthe views, and in which- Figure 1 is a side elevation of the brush.

F ig. 2 is an end view.

F ig. 3 is a vertical longitudinal sectional view taken on the line 3 3in Fig. 2, and

Fig. a is a cross-sectional view taken on the line -a in Fig. 1.

Referring more particularly to the views, the brush indicated in its.entirety by the numeral 10, consists 'essentially of a frame 11,including a casing 12 having a suitable motor 13, seated therein, ahandle 14 being provided with a shank 15 having connection betweenthe-handle and the casing, and constituting a part of the frame 11. nthe event the motor 13 is an electrical motor, the necessary wires 16are carried along the shank 15 through the handle 141-, with a suitableswitch 17 at a convenient place on the handle, the wires 16 then beingcarried to a suitable source of electrical energy. Of course it will beunderstood that I may employ some other form of motor, such as anair-driven motor -audsupply air by means of a suitable pipe or tube (notshown) and which may be carried through the handle Specification ofLetters'latent.

yand shank in the same manner as the wires '16. The casing 12 at one endthereof is provided with an opening 1,8, and immediately adjacent theopening within the casing, is disposed one end of the shaft 19 of themotor 13. A brush body 2() consisting of a substantially cylindricalelement 21 and bristles 22 secured therein, is disposed so that the bodyor main part will encircle the motor casing, and the brush body isprovided with an indented portion 23, in thev nature of a bearing andwhich has an opening 2a, through which extends the shaft 19 of theymotor, a suitable thumb nut 25 being arranged in the indented portion toengage with the shaft and rigidly clamp the brush body to the motorshaft. With this construction it will be seen that the brush body willin fact be mounted upon the casing as a bearing or support, and willhave connection with the shaft of the motor through the medium of thebody 21 and thumb nut 25.

Adjacent the inner end of the handle 14 there is provided a shield 26,which is substantially semi-circular in shape and which is suitablysecured to the shank 15 to partially encircle the brush body, thusprotecting the hand of the operator, which will be clearly seen.

In order that the free end of the brush body, or namely, that part whichis nearest to the inner end of the casing, will not bear against theexterior of the casing in the rapid rotation of the brush body, Iprovide a ring 27, which secured to the inner end of the brush body,tends to aid in properly supporting the brush body upon the casing, andthereby prevents any undue friction of the main part 21 of the brushbody with the casing.

With a brush of the character described, it will be clear that the partof the brush opposed to the shield can be brought to bear against theside of a steel plate or the hull of a vessel, and when the switch 17 isoperated to close the circuit to the motor, in the event that anelectrical motor is employed, the

tor easing Carried by the frame and rigid' With the latter, said motorcasing projecting from one side of the frame, a handle on the frame, abrush body loosely encircling the easing` and disposed to one side ofthe frame, and a segmental shield interposed between the handle and thebrush body, said handle being disposedA in ol'set relation to the frame,and lying,` in the central transverse plane of said easing7 brush bodyand said shield.

In testimony whereofl I aiix my signature.

JOSEPH GASSER.
